Abstract: 361,963. Stud-and-socket fastenings. TRIPP, E. J., Castle Inn Farm, Hanham Green, Hanham, near Bristol. Aug. 28, 1930, No. 25639. [Class 44.] A fastening for attaching doors, panels, cowlings, &c. comprises a cylindrical member 4 secured to the panel &c. 10 to be attached and housing a plunger 15 in which are pivotally mounted a pair of catches 6 normally urged to project outwards through apertures 11 in the wall of member 4, the spring action also serving to retain the head 14 of the plunger normally flush with the flanged face 9 of member 4. Member 4 is inserted in a socket 1 secured to the part 2, 3 to which the panel &c. is to be attached, the catches engaging behind the inner end of the socket, Fig. 1. The catches are released by depressing the plunger 15, Fig. 3, and may be retained withdrawn by rotating the plunger so that the catches are out of register with the apertures 11, the ends of the catches riding into an annular groove 13 in member 4. Outward movement of the catches is limited by shoulders 18 on the catches, and inward movement by abutment of head 14 against a shoulder 12 in member 4. The head 14 has ribs 16 &c. to facilitate rotation by the fingers, screwdriver, &c. An arrangement is described in which, instead of member 4 being secured to panel 10, it is tethered by a short cable so as to be removable separately to a limited distance.

Title: Improvements in the manufacture of cellulose ester fibres
Inventor: FINLAYSON DONALD
IPC: D01F2/28
Filed: 1949-10-06
Abstract: Artificial fibres of improved recoverable extensibility are obtained by extruding a solution of cellulose acetate and an isocyanatemodified or isothiocyanate-modified linear polyester-amide having rubbery elasticity in, for example, acetone, by the wet or dry-spinning methods, the relative proportions of the cellulose acetate and the modified poly-ester-amide being within their compatibility range and at most four parts by weight of cellulose acetate to each part of modified poly-ester-amide.  The fibres may be dry-spun into air or wet-spun into aqueous acetone or aqueous diethylene glycol diacetate, followed, if desired, by treatment in a regulating bath as described in Specification 654,900.  Specified modified polyester-amides are those known under the Registered Trade Mark "Vulcaprene," made by reacting ethylene glycol, ethanolamine and adipic acid to form an intermediate polymer and then heating with a di-isocyanate, e.g. a polymethylene di-isocyanate.  Yarns, prepared as above, may be stretched in the softened condition, and a voluminous appearance may be imparted by true or false twisting in the presence of steam, as described in Specification 424,880, [Group IX].  According to the Provisional Specification, other cellulose esters of acids containing not more than 4 carbon atoms, e.g. cellulose propionate and acetate propionate, may be employed, instead of cellulose acetate, and the modified polyester-amide may be replaced by modified linear polyamides or polyesters or a modified or unmodified copolymer of a conjugated diolefine and a vinyl compound containing conjugated double bonds, e.g. butadieneacrylonitrile copolymers.

Title: A new or improved mechanism for regulating the filling of moulds, in moulding-machines, and the ejecting of moulded articles from the said moulds
IPC: B30B15/32
Filed: 1937-09-24
Abstract: 502,809. Stationary-mould machines. HUMPHRIS, F. Sept. 24, 1937, No. 25899. [Class 87 (ii)] Relates to means for controlling the amount of material fed into a mould of a stationarymould machine having upper and lower plungers. After the lower plunger e has raised a moulded article level with the upper surface of the mould, it is lowered to a position determined by the position of a cam-operated lever b that is adapted to be engaged by a camoperated lever d for actuating the lower plunger. The mould is filled by a slide fed from a hopper. The lower plunger is then lowered against an abutment p, and the upper plunger descends and moulds the article. The operative position of the lever b is adjusted by varying the length, by rack and worm mechanism, of a shaft h to which the lever b is pivoted. The lever d is formed with an arm k that is engaged by the cam f for moving the plunger e into its lowest position. A weighted lever k<4> may be employed to ensure that the plunger falls into the intermediate position determined by the lever b. Fig. 1 shows a filled mould c, the filling slide x, and the lower plunger e in its intermediate position.

Title: Method for producing granular products
IPC: C01D5/00
Filed: 1965-06-18
Abstract: A method of pelletizing particulate water-soluble crystalline potash salts such as potassium chloride, potassium sulphate or the double sulphate of potassium and magnesium, comprises extruding the salt, when provided with a water content of between 5% and 13% by weight and at a temperature between 50 DEG  F. and 180 DEG  F., through an orifice, whose diameter lies between 0.07 and 0.25 inch, and cutting the extrudate to form cylindrical pellets having a length of between 1 and 10 times the diameter thereof. Urea may be added to act as a lubricant in an amount between 0.2-2% by weight of the mixture.  A preferred extrusion machine is that of the ring and roller type and the extrusion orifice from inlet to outlet is preferably in three parts, viz.: (i) a converging portion having an apical angle between 10 and 50 degrees, (ii) a cylindrical portion whose length is between 1 and 10 times its diameter and (iii) a diverging portion having an apical angle between 3 and 30 degrees.  The water content of the salt may be adjusted by drying a wet filter cake thereof in a rotary drier or moistening the salt in a pug mill.  The mesh size of the particulate salt may lie between -14 and -300 with a size of -100 mesh being most appropriate.  According to the invention the production of shape retaining pellets is due to the formation of heat during extrusion with consequent flashing of a portion of the moisture content and precipitation of material which forms bonds at the crystalline interfaces.  The pellets may be dried at an elevated temperature which is normally above 212 DEG  F.

Patent GB-665058-A (GB)
Title: Improvements in and relating to the preparation of alkylation products
Filed: 1949-10-11
Abstract: Alkylation products having the viscosity of a thin lubricating oil are prepared by reacting an alkylatable aromatic compound having a boiling point between 110 DEG  and 210 DEG  C., such as toluene, xylene, mesitylene, ethyl benzene, cumene, cymenes, durene, phenol or aniline, with a straight chain olefin, preferably an a -olefin, of 14-18 carbon atoms, in the presence of an alkylation catalyst, using about 1.5-5 mols. of aromatic compound for each mol. of olefin. Mineral oil fractions such as kerosine rich in aromatics may be used as such or extracted with, for example, liquid SO2, furfural, nitrobenzene, or antimony trichloride and the extract used.  The most readily alkylatable aromatics may first be removed by a pre-alkylation with olefins of 14-18C atoms, or less.  Aromatics may also be recovered by percolation over silica gel or floridin.  The olefins may be obtained by cracking, and the cracked distillates freed from diolefins by heating with AlCl3.  Alkylation is effected at about 20-100, preferably 20-70 DEG  C., using Friedel-Crafts' halides or sulphuric acid. With AlCl3, an amount of 0.5-10, preferably 1-4 per cent by weight is used.  Catalyst sludge from a previous alkylation may be re-used as catalyst, if desired with or prior to fresh catalyst.  Reaction times may be from 3/4 -6 hours. After sludge removal, the product is treated with alkali such as lime, and with bleaching earth, for example in a combined treatment at 150-240 DEG  C. in an inert atmosphere, and is vacuum distilled. The unconverted portion separated may be repeatedly recycled together with fresh aromatic extract, to another alkylation.  In examples: (1) an aromatic kerosine extract boiling at 150-210 DEG  C. is reacted with a C14-C19 fraction separated from a cracked paraffin wax, after first treating with AlCl3 at 80 DEG  C., AlCl3 being used as catalyst at 40 DEG  C.; (2) toluene is alkylated with the cracked product of (1); (3) the same cracked distillate is reacted with an aromatic extract boiling at 160-210 DEG  C., using AlCl3 at 40 DEG  C., the unconverted part of the extract being further alkylated with additional cracked distillate in six successive alkylations.  The viscosity of the products first decreases to a minimum then increases; (4) the aromatic extract and cracked distillate are alkylated, part of the unconverted extract being mixed with fresh extract and further alkylated, the product after repeating six times having substantially the same properties as the first.
